The inline fuses are common problems - not the fuses but the contacts in the fuse socket. Three years back the one on Rhapsody had a real high resistance connection and burnt the socket. The marine environment is not kind to these critters. I cut the wire and used a butt splice with heat shrink for the replacement fuse socket. I believe Vee Jay had a similar problem and replaced the cartridge fuses with a blade type fuse socket.
